## Affects

***

Teams that consume Lender streaming contracts or operate Consignado M011 portability discovery.

## What changed

***

Lender's streaming catalog has 35 definitions: 33 facts and two commands. Individual consumer and producer paths remain configuration-gated, so a catalog definition is not necessarily live in a deployed runtime.

M011 portability discovery is independently enabled with `LEILAO_PORTABILITY_ENABLED=true`; it requires `LEILAO_TENANT_ID`, Dataprev, streaming, a primary database, and the canonical outbox. It does not require `LEILAO_ENABLED=true`. This corrects documentation of implemented contracts; it does not announce a runtime release.

## Impact

***

**Classification: Review recommended.** Event consumers and portability operators should verify the deployed manifest and configuration before enabling or depending on these paths.

## What you need to do

***

<Steps>
  <Step>Check the deployed Lender manifest before treating a catalog definition as a live integration.</Step>
  <Step>Configure the M011 prerequisites and a portability listing window wider than the discovery interval plus clock-skew margin before enabling discovery.</Step>
  <Step>Do not use `LEILAO_ENABLED` as a prerequisite for M011 portability discovery.</Step>
</Steps>

### Deadline

Review before enabling a Lender streaming integration or M011 discovery.
